The graph shows development of specific CO2 emissions, defined as emissions of CO2 per transport unit (tonne-km), by freight transport mode (road, rail, maritime, inland shipping) over the period 1995 to 2009.
Specific CO2 emissions data for all transport modes are modelled data derived from TREMOVE (http://www.tremove.org/model/index.htm) and TRENDS (http://www.forum.europa.eu.int/Public/irc/dsis/pip/library?l=/environment_trends).
Specific CO2 emissions are expressed in grams per tonne-kilometer.

Use a toy library and if there isn't one in your neighbourhood, start one!
Instead of buying new toys, set up a toy library with your friends and exchange them. The variety of toys will entertain the kids and they will be used by more than one child thus reducing your impact on the environment.
